In XINS the functions are initialised when you start the server, the
initialisation also passes the properties defined in
xins.properties to the function. XINS has the notion
of shared instance which is an object created and initialized in a similar
way as functions are. Furthermore this object is passed as an instance to
all the defined functions of the API.
You can think about the following situations:
You want to access a database or an access to LDAP with the
access properties set in xins.properties.
You want to share data between functions.
To add a shared instance to the API add in the
impl.xml file <instance
name="_sharedObject" getter="getSharedObject" class="SharedObject"
/>.
Now you need to create a class SharedObject
in the implementation package that extends the
org.xins.common.manageable.Manageable class (javadoc).
Now you could use this object by calling in the call(Request request) method
// Get some data from the shared object String firstName = _sharedObject.getFirstName(request.getLastName());
An example is provided in the allinone
project.
